ButtonTypeInterface

Builds the form.

This method is called for each type in the hierarchy starting form the top most type. Type extensions can further modify the form.

Builds the form view.

This method is called for each type in the hierarchy starting form the top most type. Type extensions can further modify the view.

A view of a form is built before the views of the child forms are built. This means that you cannot access child views in this method. If you need to do so, move your logic to {@link finishView()} instead.

Finishes the form view.

This method gets called for each type in the hierarchy starting form the top most type. Type extensions can further modify the view.

When this method is called, views of the form's children have already been built and finished and can be accessed. You should only implement such logic in this method that actually accesses child views. For everything else you are recommended to implement {@link buildView()} instead.

Sets the default options for this type.

Returns the name of the parent type.

You can also return a type instance from this method, although doing so is discouraged because it leads to a performance penalty. The support for returning type instances may be dropped from future releases.

Returns the name of this type.
